Damage evaluation in a concrete gravity dam using Smoothed particle hydrodynamics

An unexpected failure of a concrete gravity dam may cause unimaginable human suffering and massive economic losses. An earthquake is the main factor contributing to the concrete gravity dam\u27s failure.

Dam-reservoir interaction effect on the seismic response of concrete gravity dams

, 1997
A study was conducted to investigate the dam-reservoir interaction effect on the linear and nonlinear seismic response of concrete gravity dams. A mathematical approach was developed for the solution of the coupled dam-reservoir interaction problem which

Design of high concrete gravity dam and its stability analyses for varying earthquake intensities

, 2009
Gravity dams are solid concrete structures that maintain their stability against design loads from the geometric shape and the mass and strength of the concrete. The various forces affecting the design of a gravity dam are dead load or stabilizing force,

Seismic testing of a scaled roller-compacted-concrete gravity dam

, 2016
Within the last half-century, seismic response analysis of concrete gravity dams has been extensively studied. Studies reveal that two types of failure modes prevail in the form of dam body cracking or base slide. The literature lacks the conditions that

Seismic Response Evaluation of a Concrete Gravity Dam Considering Dam-Reservoir-Foundation Interaction

, 2019
The observation of the behavior of concrete gravity dams that are exposed to seismic loads is the main factor for the safety evaluation of the dams. In this regard, dam-foundation-reservoir interaction can be seen as one of the most significant concerns ...
